Ever since I moved I've had a reeeeeeeeeeally short commute .. 1.3 miles ! If I grab a coffee , then it's 2 miles tops . Question is , am I harming the engine with such short runs all the time ? I keep it in the underground parking , so warm starts in the AM , but cold starts at end of shirt . If this is going to cause any adverse engine / plug concerns , what can I do to avoid them . Do I go around the block a few times , idle longer ... walk to work ? One last thing , would ambient temp ( ie : summer vs winter ) manifest itself in all this ? Thanx !
